WARNING
q
q
Do not touch or remove electrical parts
when starting or during operation.
Keep hands, hair, and clothes away from
the flywheel and other rotating parts
while the engine is running.

Be sure the outboard motor is securely
fastened to the transom or a stable
stand.

CAUTION:
CAUTION:
This procedure must be performed while
the outboard motor is in the water. A flush-
ing attachment or test tank can be used.
q
Do not overfill the oil, and be sure the
outboard motor is upright (not tilted)
when checking and changing the engine
oil.
If the oil level is above the upper level
mark, drain until the level meets the
specified capacity. Overfilling the oil
could cause leakage or damage.
A diagnostic tachometer should be used for
this procedure. Results may vary depending
on whether testing is conducted with the
flushing attachment, in a test tank, or with the
outboard motor in the water.
q
1.
Start the engine and allow it to warm up
fully in neutral until it is running smoothly.
ECM01240
CAUTION:
Change the engine oil after the first 10
hours of operation, and every 100 hours or
at 6-month intervals thereafter. Otherwise
the engine will wear quickly.
NOTE:
Correct idling speed inspection is only possi-
ble if the engine is fully warmed up. If not
warmed up fully, the idle speed will measure
higher than normal. If you have difficulty veri-
fying the idle speed, or the idle speed requires
adjustment, consult a Yamaha dealer or other
qualified mechanic.
NOTE:
Change the engine oil when the oil is still
warm.
1.
Put the outboard motor in an upright po-
sition (not tilted).
2.
Verify whether the idle speed is set to
specification. For idle speed specifica-
tions, see page 30.
